Brick con bootloader locked!

[romhunter]

Hola. Tengo un Moto G3 (XT1540 con 1GB de RAM) que originalmente traía Android 5. Hace un par de días, tuve una notificación de actualización del sistema y luego de realizarla el teléfono quedo en un bootloop (Logo de Motorola, apagón, logo de Motorola, apagón ...).
Estuve investigando un poco acerca de la solución e intenté rescribir la ROM stock, el problema es que no puedo desactivar el bootloader (con el comando: fastboot oem unlock S7UHNG ...) porque me sale el mensaje:

(bootloader) slot-count: not found
(bootloader) slot-suffixes: not found
(bootloader) slot-suffixes: not found
...
(bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)

La verdad, no pensé que podría fallar la OTA y nunca activé esa opción mientras mi teléfono estuvo funcionando

De todas maneras, estuve probando escribir estas ROMs con el bootloader bloqueado:
* XT1540_OSPREY_RETLA_NA_6.0_MPI24.65-25_cid12_subsidy-DEFAULT_CFC
(MD5: 4a57370d1129ae9a2584760a61028127)
* XT1540_OSPREY_RETLA_NA_6.0_MPI24.65-33.1-2_cid12_subsidy-DEFAULT_CFC
(MD5: e8b2bc9de8ce3cc86d27a11ee1614fea)
* XT1540_OSPREY_RETUS_6.0_MPI24.65-25.1_cid9_subsidy-DEFAULT_CFC
(MD5: 18bb2954fe2537e8c1f6bcfcf82b0755)

Todas me llevaron al bootloader, con los mensajes:
AP Fastboot Flash Mode (Secure)
version downgraded for boot
failed to validate boot image
ERROR: Failed to pass validation, backup to fastboot
Fastboot Reason: Fall-through from normal boot mode

Antes de loa primer escritura hice los wipes de la cache y los datos del usuario

El comando "fastboot getvar all", actualmente me devuelve el siguiente resultado:

Está claro que en este caso la responsabilidad es de Motorola, ¿por qué no haces uso de la garantía?

[romhunter]

Hola. Mmm ... no creo que se pueda lo de la garantía. Ya hace bastante que tengo el teléfono. ¿Dónde tendría que hacer el reclamo? No tengo relación directa con el vendedor porque la compra la hice por Internet. Gracias por la resuesta. Saludos
